WHAT'S UP WITH YAHOO
Yahoo's results are now served from MSN/Bing. If you are interested in the history of Yahoo, read on.
Well, Yahoo bought Inktomi, All the Web, Overture (and Alta Vista as part of the deal). All the Web & Alta Vista were promptly put on the back burner, with no further development assigned to the search engines but with the indexes kept alive. Yahoo announced a new product called Overture Site Match (not to be confused with Overture keyword bidding). Site Match has a registration fee of $49 for the first URL and a click through cost on Tier One of 15 cents (mostly non biz type of stuff) or Tier Two of 30 cents for most business categories for every search that goes from Yahoo to your site. It seems excessively GREEDY to me and, even for a medium sized business, it is out of reach at what can easily become hundreds to thousands each month. Better to invest in keyword bidding to ensure your results with Yahoo, in my opinion. Just to make sure their own newly acquired Inktomi users wouldn't get inclusion for the one time yearly fee, Yahoo purged out Inktomi listings as of April 15th and bombards subscribers with non opt in email marketing through business partners pushing Inktomi customers to Site Match.
Yahoo appears to be giving fair weight to its directory listings which are still available for $299 US per year, whereas before, they always came after Yahoo's Google web index listings. I not a big fan of paying $299 a year for their directory listings either. The GOOD news is that you can get on Yahoo for free, if you don't mind waiting two months, and this is part of SEO's standard registration, or you can keyword bid to place. Besides, even if you don't pay, Yahoo will eventually find you via links to your site, but don't count on good placement in competitive searches.
Yahoo's algorithm called SLURP behaves very much like Google's and the old Inktomi algorithm, although they display differently than the pure Inktomi driven HotBot results by example. Yahoo places significant weight on the description and title tag, where Google only cares about title.
Yahoo does not follow image links. Yahoo's spider cannot follow frames pages, flash, or dynamic pages but is very adept, like Google, at following links around your site. Therefore, html page links and site maps are essential. I'm not sure how Yahoo will gain market share on Google with a strategy like this, but they are certainly making new profit by dragging more $ away from their listings. Let's see now - reduced market share, higher profits as a result of higher advertiser costs are a recipe for???
